Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Ground describes, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments. Based on embodiments of the invention, the institute that those of ordinary skill in the art are obtained under not making creative work premise There are other embodiments, broadly fall into protection scope of the present invention.

Self is entirely sealed in pressure line by the present invention with the p-wire of insulating barrier, make p-wire and confined pressure liquid every From, it is ensured that the signal of telecommunication is stable and improves pressure performance.And for consolidated model and the different characteristics of core model, The terminals of saturation probe seal with exit end face junction with model surface, p-wire, it is ensured that testing liquid Or confined pressure liquid will not be revealed by p-wire.

Respectively consolidated model and the sealing device of core model and operation principle thereof are carried out specifically below in conjunction with accompanying drawing Bright.

(1) consolidated model

P-wire without special protection is collected in confined pressure space by the p-wire sealing means of existing consolidated model, logical Crossing the unification of the honeycomb seal plate on autoclave outer wall and lead to space outerpace, inside and outside this sealing plate, two end faces are all difficult to close Envelope, compressive resistance is low, and the seepage of a hole point i.e. causes the inefficacy of integral experiment;Without special protection conductor wire with Between rubber, confined pressure liquid easily infiltrates into rubber, causes the situations such as line short.

Embodiments provide the pressure-resistant seal device of a species saturation measurement circuit, it is adaptable to consolidated model.Figure 1 is the consolidated model sealing schematic diagram of the embodiment of the present invention, as it is shown in figure 1, this device includes autoclave 11 and position Consolidated model 12 in autoclave 11, consolidated model 12 outer surface is provided with sealant 121, and sealant 121 is with high Region between pressure still 11 is full of confined pressure liquid 13, and saturation measurement circuit includes: saturation probe 14 and with saturated The p-wire 15 that the terminals of degree probe 14 connect, saturation probe 14 stretches in consolidated model 12, p-wire 15 Sequentially passing through sealant 121, confined pressure liquid 13 and autoclave 11, p-wire 15 is the conductor wire with insulating barrier;

Wherein, the outer sheathed pressure pipe 16 of p-wire 15;Terminals 141 (the i.e. p-wire 15 of saturation probe 14 With the junction of saturation probe 14, see Fig. 2), p-wire 15 all use entirety with the junction of pressure pipe 16 Injecting glue seals, and is respectively positioned in sealant 121;Pressure pipe 16 passes autoclave 11, and its exit end face arranges pressure Cap 17 seals.
